🧠 Why Iron Matters More Than You Think
Iron isn’t just about avoiding fatigue—it’s a key player in muscle performance, brain function, and sleep quality. It helps shuttle oxygen through your bloodstream and into your muscles where it powers every lift, sprint, and recovery.
Low iron = low power, low stamina, and that frustrating “why am I so tired?” feeling—even with solid training and nutrition.
Klean Iron helps you fix that fast—without the gut issues most iron pills cause.

Frequently Asked Questions
Klean Iron uses 27 mg of Ferronyl® iron carbonyl, a highly bioavailable form of iron that’s gentle on the stomach. Unlike many iron pills, it minimizes gastrointestinal discomfort while maximizing absorption.
Iron is essential for oxygen delivery to your muscles. Athletes, especially endurance trainers and women, often have higher iron demands. Low iron can lead to fatigue, reduced stamina, and slower recovery.
By supporting red blood cell production, Klean Iron enhances oxygen transport throughout your body. This means improved muscle strength, endurance, and overall energy during and after workouts.
Yes, when taken as directed (1 tablet daily without food). It’s NSF Certified for Sport®, meaning it’s third-party tested for purity and banned substances, making it safe for competitive athletes.
Common symptoms of low iron include fatigue, low endurance, pale skin, frequent dizziness, and poor recovery. If you experience these, consult with a healthcare professional to determine your iron levels.
Yes! Vegetarians often have lower iron intake since plant-based diets can lack easily absorbed heme iron. Klean Iron offers a highly bioavailable source to help fill that gap.
Iron supports brain function and mitochondrial health, which can lead to better mental clarity and improved sleep patterns—especially in individuals with low iron stores.
Yes, but avoid taking it alongside calcium or high-dose zinc as these can interfere with iron absorption. It pairs well with vitamin C supplements, which enhance absorption.
Many users report feeling increased energy and reduced fatigue within 4–6 weeks, as studies show Ferronyl® iron effectively raises iron levels and enhances endurance over time.
Those with iron overload disorders, or anyone not deficient, should avoid excess iron. Always consult your doctor before starting iron supplements, especially if pregnant or under medical care.
